' PAPER AND FABRIC.-

No Drawing.

To all whom it may concern:

Be it known that I, ARMIN a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain newand useful Improvements in Papers and Fabrics, of which the following is a speci; fication. I

This invention relates to the manufacture of sheet materials which have waterproof qualities and in some instances are in imitation of leather. I

- It is one of the objects of the invention to provide a paper sheet or fabric that will property of straightening out into a flat not only be waterproof but which will not crack or become permanently wrinkled in ordinary use and will also be comparatively inexpensive to manufacture.

Another object of the invention is to provide a coated fabric in imitation of leather which will possess many of the desirable characteristics of a rubberized fabric.

Another object of the invention is to provide an inexpensive transparent paper of unusual strength and durability which will not lose its tensile strength or transparency where wrinkled or folded.

Other objects and the features of novelty will become apparent from the following description.

I have discovered that by impregnating a sheet of paper or other absorbent fabric of Y a flexible nature, such as a woven fabric, with a solution or mixture containing polymerized cumarone and a vegetable oil, the sheet will be rendered waterproof, and .in the case of a woven fabric will have the like. 1

As an illustration of one method of practising'the invention I heat a quantity of a vegetable oil, such as China wood oil, linseed Specification of Letters Patent.

oil, poppy seed oil or soy bean oil and add the polymerization products of the cumarone and indene group until the mixture is of thedesired consistency. Ordinarily the proportlon of cumarone and indene is at least one half the amount of oil and this results 1n a hard homogeneous mass when cold. This is heated and mixed with a volatile solvent suchas one of the commonly used hydrocarbon solvents to form a liquid. The

consistency of this liquid mixture, will vary 1n accordance with the material to which it is to be applied. For paper a very thin mix-' ture is used and the paper may be dipped into the mixture or the latter may be applied w1th a brush or in any other suitable manner. The volatile solvent evaporates and leaves the paper impregnated with the mixture of oil and cumarone.

Woven fabrics may be treated in the manner above described. When an imitation of leather is desired the fabric is impregnated and'also coated with a similar mixture to which the requisite pigment has been added.

Having thus described my invention, what I claim and desire to secure by Letters'Patent is: I 1. A new article of manufacture consisting of a sheet of absorbent material impregnated with a mixture, containing a vegetable oil 4 and polymerized cumarone.

2. A new article of manufacture consisting of a sheet of. absorbent material impregnated with a mixture containing a vegetable oil and the polymerization products of the cumarone and indene groups.

3. A a new article of manufacture consisting of a flexible sheet of absorbent material, having applied thereto far-mixture containing China wood oil and the polymerization products of the cumarone and indene groups.

4:. A new article of manufacture consisting of a flexible sheet of absorbent material, having applied thereto a mixture containing a vegetable oil and the polymerization prodnets of the cumarone and indene groups.

5. A new article of manufacture cons1st-.

ing of a fabric, having applied thereto a mixture containing China wood oil and the polymerization products of the cumarone and indene groups.

6. A new article of manufacture consisting of a fabric, having applied thereto a mixture containing a vegetable oiland the polymerization products of the cumarone and indene groups.

7 A new article of manufacture consisting of a sheet of paper impregnated with a mixture containing China wood oil and the polymerization products of the cumarone and indene groups.

8. A new article of manufacture consisting of a sheet of paper impregnated with a mixture containing a vegetable oil and the polymerization products of the cumarone and indene groups.

9. A new article of manufacture consisting of a sheet of paper, having applied thereto a mixture containing China wood oil and the polymerization products of the cumarone and indene groups. p,

"10. A new article of manufacture consistingof a sheet of paper, havingapplied theretoamixture containing a vegetable oil and thefpolymeriz'ation products of the cuma-. rone and indene groups. y

'11. "A new article of'manufacture consist ing of-a woven fabric, having applied thereto a mixture containing China wood oil and the polymerization productsof the cumarone and indene groups, and having a coating of a similar mixture with or without a pigment therein.

12. A new article of manufacture consisting'of a woven fabric, having applied thereto a mixture containing a vegetable oil and .ucts of the cumarone and indene groups,

and having a coating of a similar mixture with or without a pigment therein.

14. A new article of manufacture consisting of a woven fabric of absorbent material,

having applied thereto a mixture containing a vegetable oil and the polymerization products of the cumarone and indene groups, and

having a coating of a similar mixture with or without a pigment therein.

' 15. A new article of manufacture consisting of a woven fabric coated with a mixture containing China wood oil and the polymeri-- zation products of the cumarone and indene groups.

16. A new article of manufacture consisting of a woven fabric coated with a mixture containing a vegetable oil and the polymerization products of the cumarone and indene groups.

In testimony whereof I affix my signature.
